Specification of Letters Patent.

Patented Apr. 2, 1918.

Application filed June 9, 1917. Serial No. 173,767.

To all whom it may concern:

Be it known that I, SAMUEL S. CORNELIUS, a citizen of the United States, residing at Commerce, in the county of Hunt and State of Texas, have invented a new and useful Furnace, of which the following is a specification.

The present invention appertains to furnaces,- ant. aims to provide a noveland improved furnace adapted especially for use outdoors for heating a wash pot or kettle.

is tl e object of the invention to pro-' vide a furnace of the nature indicated which is simple and inexpensive in construction, and which embodies a novel assemblage of the component elements, the device having novel means for accommodating the kettle.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arran ement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a front View of the furnace, portions being broken away;

Fig. 2 is a plan view with the kettle cover and bail removed, and portions broken away and shown in section;

Fig. 3 is a detail view of the upper end of one of the upright supporting bars.

The casing 1 of the furnace is formed from a plate of sheet metal set on edge and bent so that its ends overlap, as at 2, at the rear of the furnace. A vertical supporting and stiffening bar 3 is riveted or otherwise secured to the inner overlapped end of the plate, and the overlapped portions are clamped together by a suitable number of bolts 4: which also preferably extend through the bar 3, the outer overlapped portion. having slots 5 for the bolts 4 in order that the casing can be adjusted to accommodate various kettles or pots. Upright supporting bars 6 are suitably secured to the side walls of thejacket at the interior thereof. The bars 3 and 6 serve to strengthen the casing and relieve the same of undue strains, the lower ends of the bars being bent back inwardly, as at to provide feet, and to'also provide shoulders or ledges for supporting the grate 8 between the bars above the ground on which the easing is set. The grate S is used when coal is burnt, but can be eliminated when wood is used as fuel. The front wall ofthe casing 1 has a fuel. door 9, and is also provided with a draft damper 10 for controlling the flow of air into the casingbelow the grate. Suitable handles 11 are attached to the side walls of the casing 1 near its upper end in order that the casing can be readily carried. 7

The upper ends of the bars 6 are notched, as at 13, to support the outstanding ears or eyes 14; at theopposite sides of the rim of the kettle 15, whereby the bars 6 sustain the greater portion of the weight of the kettle and its contents.

The cars 14: in seating in the notches 13 hold the kettle in proper position, and the upper edge of the casing 1 projects above the bars 6 to surround the rim of the kettle.

The cars 14 have the usual bail l6 connected thereto in order that the kettle can be readily handled. The bars 6 being disposed at opposite sides of the kettle and grate bulge the side walls of the casing 1 outwardly, as at 17, to provide crescent shaped outlet flues 18 for the products of combustion which circulate around the walls of the kettle for heating it. The kettle 13 has a cover 19 provided with a handle 20. The rim of the kettle seats upon the front Wall of the casing 1 and upon the upper end of the rear bar 3.

Then the furnace is used with small kettles or pots, the supporting bars 3 and 6 can be eliminated, and the rim of the kettle or pot can rest directly on the upper edge of the casing which is contracted to embrace the kettle or pot, the outstanding cars 14 of the kettle serving to bulge the upper edge of the casing outwardly for the outlet of the products of combustion.

Having thus described theinvention, what is claimed as new is:

1. A furnace embodying a casing adapted to receive a kettle, the casing being adjustable to receive kettles of different sizes and having means for preventing undesired expansion thereof, and upright bars secured interiorly to the walls of the casing for supporting the kettle and bulging the casing outwardly to provide outlet flues.

2. A furnace embodying a casing adapted to receive a kettle, upright bars secured interiorly to the walls of the casing lfor supporting the kettle and bulging the easing outwardly to provide outlet flues, said bai's having ledges near their lower ends, and a grate seatable upon said ledges between the bars to assist in bulging the casing.

3. A furnace embodying a casing for receiving a kettle, and a paiivof'opposite upright bars secured interiorly to the Walls of the casing and having their upper (ends notched to support the ears ofthe ket'tle,

said bars bulging the corresponding walls -01": the casing outwardly to provide outlet flues ffor the products of conibustionand *to receive said ears.

A furnace embodying a casing comprising a plate set on edge and bent so that its ends overlap, adjustable means for clamping 'the overlapped portions together, qnposite bars secured interiorly to the Walls of the casing and arranged in an upright position eior supporting a kettle ,therebetween and bulging the casing outwardly to iprovitleioufiletiflues.

In testimony that I claim the foregoing as my own, I have #hereto :afiixed .niy signature in the presence of two witnesses.

SAMUEL is. CORNELIUS.
